Question help!

[popcoin]

last night I was playing rust like usual and the pc completely shut off with no warning or even lag previous to shutting down, just straight to a black screen in an instant

I waited a little moment and booted back up and all was fine no lag or nothing so went back on rust, after about 20 mins it did the exact same again so I just left it and went off

Tonight I went to start the pc, it lit up for a second and then all went black, soon after it started making a quiet crackling noise so I just unplugged.
Capacitors look fine, I'm just thinking to order a new PSU and see if that helps

any help is appreciated.

For anyone to start to diagnose, they'd need a full parts list of the system.
Make/model of everything.

And the very relevant part, the PSU?

Well, yes.
But be patient...I asked for the parts list just as a starting point, for someone to potentially diagnose the problem.

It is a first suspect, not sure if same series but a while ago some MSI PSUs had that problem. I recently had similar problem but found out that power cable was loose at input to the PSU. Changed to more solid cable.
